Meow Alert? Ali & Vienna's Surprise Facetime

What happens when Ali Fedotowsky and Vienna Girardi run into each other? Does a catfight erupt? Or would all their chatting make Jake Pavelka's ears burn?

Read on to find out…

Ali was browsing the swag at the Kari Feinstein Style Lounge at Montage Beverly Hills yesterday when Vienna showed up to do the same.

"Vienna kind of smirked when she was told at the front that Ali was there already," a source reports. "They ignored each other the whole time until Ali went to hug Vienna."

Too bad the two aren't a bit more feisty. Just imagine what it would have been like if the claws really came out. "They said 'hi' briefly," the source said. "Ali was more friendly than Vienna, but they only interacted for a few seconds."

Before they went their separate ways, Vienna told Ali she thought Roberto Martinez was a "good choice."
